To all whom it may concern:

Be it known that. I, ANDREW Bonenss, of Owego, county of Tioga. State of New York, have invented a new and useful Improvement in Magazine Fire-Arms, of which the following, in connection with the accompanying drawings, is a specification.

Figure l is a vertical. longitudinal sectional view of this arm; Fig 2, a top view. Fig. 3 is the rotating or looking part of the breechbolt. Fig. 4 is thecontinuous bolt; Fig. 5, the firing-pin; Fig. 6, a side view of the arm, showing the loading-apcrture and a trap or gate for closing it. Figs. 7 and 8 show modifications of the loading-trap. Fig. 9 is a view similar to Fig. l, but in a locked position and cooked; Fig. 10 shows the parts of the bolt detached.

similar letters of reference indicate corresponding parts.

A is the frame or receiver; B, the bolt; B, the locking-piece of the bolt; Z), the incline to withdraw the firing-pin B, the cocking-piece carrying the firing-pin; c, the carrier; 0, an

elastic buffer 3 r, the ejector and stud to raise the carrier; (1, a dog to take up the shock of the closing-bolt and assist in opening it; and

T, the loading-trap or cover.

In this arm the magazine delivers the cartridges from beneath. the barrel. to the carrier rises it springs the feeding cartridge forward partly into the chamber, so that the ball may not rise too high or catch on the top of the chamber.

The belt is made in three principal parts, the main part I, being continuous, the rotating part B inclosi ng a part of it, and the part B incloses its rearward portion, while the firing-pin p passes through its front. The nut a holds 1 forward, the nut aconlines the spiral n'iains n'ing, and the incline i locks down the extractor. I

The rotating part 13 of the breech bolt is provided with dog (I, and the frame has a notch, d, to engage the point or free .end of said dog, which is pressed toward or into aforesaid notch by a sp'rin g, d.

The firing-pin p has a thumb-piece, B", attached thereto, and so arranged at the side and top of the armthat the piece may be cocked by it as by an ordinary hammer without moving the locking mechanism of the breech.

The ejecting-stud r has a limited longitudieject the cartridge or shell, and its lower projection, striking the'point 1' when the bolt is withdrawn, raises the carrier.

The trap T, Figs. 7 and S, is to cover or close the side-loading aperture, as shown in Fig. 6. Said trap oscillates laterally in a cut out in the inside of the frame, and is pressed the insertion of the cartridges into the magazine this trap is pressedout, as shown in dottedlines in Fig. 6; but if a double trap is used, as shown in Fig. 7, it can open enough to admit a cartridge without projecting from the frame.

It is obvious that this trap T can, be hung forward instead of in the rear of the loadingaperture, in which case it will be scored out on dotted lines 13 t, as shown in Figs. 7. and 8, to allow the point of the eartridgeto press the trap open, instead of at t t. The pin sidewise.

part B. This withdraws the firing-pin by the locks the extractor tightly to the shell by the incline "i pressing on it. The point of the dog (6 enters the notch d of the frame, as shown in dotted lines in Fig. 2, and forces the pivot of the dog to describe an arc of a circle of which the notch d and point of the dog" must continue the center, and thereby force the pivot back to .r, Fig. 2, when the breech is fully unlocked. This constitutes a powerful rounded or beveled locking-shoulder permitting the movement as described. Then by drawing back thebolt in the usual manner, the

ejector strikes the stud r to expel the shell nal motion relatively to the ln'ecch-bolt, to
